Burned my lawn badly
I burned my lawn badly by applying two 'coats' of fertilizer. I finished the first 'coat', and there was a lot of fert still left in the spreader. I figured that the cable on my Scotts broadcast spreader had stretched and it wasn't putting out as much fert as it should be, so I did the front lawn again.
This was with Lesco Weed and Feed back in the middle of June. The lawn slowly turned brown - the grass started to look like it does in the middle of the winter. In the middle of July, the color started to come back a little - I figured it was recovering. At that point I put down one coat of Lesco Turf Fertilizer (I believe the nitrogen number is 24). Since then the front lawn has gone back to brown. We have had a few hot spells, and that seems to make the brown spread more and look worse.
Have I killed the lawn, or will it come back? What should my plan be?
